Improved seat design (new cosine-curve seat) with rib disc (*except 40mm type) can provide a larger flow rate and larger Cv value than existing models by maintaining mechanical strength of the disc.

ULTRA SUPER LIGHT WEIGHT

Easy installation due to lighter weight (30% lighter than 702Z on 200mm types) and alignment ribs.

REMARKABLE ANTI-CONDENSATION CAPABILITY

Better anti-condensation capability is achieved by utilizing a high performance engineering plastic column.  The high performance engineering plastic has excellent features such as low water absorption, high corrosion resistance, heat resistance, nonflammability as well as shock resistance, which is approximately four times that of hard PVC material.
